DVR playback

Access Anchor Anchor x2

You can view recordings using administration web interface.

Also you can access this recording by special URLs, that will be described further.

There's two modes: stream mode and file mode.
A file dieffers from a stream so that it is finite. That is, when viewing a file, a player will show rewind bar, and available for viewing video section will be limited (it will have a beginning and an end). When viewing a stream rewinding does not appear because there is no end.
You can see this difference is in URLs too. Eg file URL may end with "index-1345345345354-3600.m3u8" (limits are defined: beginning at 1345345345354 and end after 3600 seconds), or stream URL may end with "timeshift_abs/1345345345354" (only beginning is defined).

Electronic Program Guide (EPG) Anchor Anchor x2

DVR can be used with EPG. The modern approach to the provision of television archive - record the entire video, and then provide access to the archive (or rewind current video) using the EPG.

All metadata will be stored in a middleware and Flussonic Media Server will provide access to this archive as an infinite tape.

Two modes exist:

  • view already recorded video
  • view live

If the show is already over, the middleware based on EPG forms the link to view the archive. The user can see the recorded movie as a normal file. For example, if the show is started at 18:15 Moscow time (14:15 UTC) on August 27 and continued for an hour, the middleware should create URL like this: http://flussonic:8080/ort/index-1409148900-3600.m3u8.

If the show is not over, the middleware may create special URL to the archive, that allows to rewind live to its beginning.
Unfortunately this feature supported on a few devices and STBs, but nevertheless it exists.
URL for this unfinished video will be like this: http://flussonic:8080/ort/index-1409148900-now.m3u8

Viewing from the administration web interface Anchor Anchor x2

You can view contents of an archive using Flussonic Media Server web interface. Press stream name on the Streams screen under the Media tab, then press DVR tab. Timeline bar should be displayed and video will be played in real time.

Timeline

Timeline bar have a several zones indicated with different colors. Red color means no recording at this time, green is for available video, and blue is for current time.

Navigation

You can click anywhere on the timeline bar to begin playback of the video starting from that time. Also you can use buttons on the left and right of the timeline to browse the video:

  • "-" and "+" for “zooming” a time period, so you can select a time more precisely
  • "<" and ">" for moving a time period to an earlier or later time

Also you can enter any date in the text field under the timeline to open an archive at this date.

Exporting

You can select a part of archive to export a video file in MP4 format. Just move gray limiters on the left and right. You'll see that date under the timeline has changed. Save the file by clicking Export MP4.
